Talking with Sandy and Paul about More Cores for Hall D

  • new multi-core queue will be put up: 12 core qualifier, 4 jobs max
  • 30 new nodes (16 cores each) coming in to farm from LQCD as loan payback. Will be part of multi-core queue.
  • 50 of the 100 nodes currently in the exclusive queue moving to the multi-core queue.
  • Most of the exclusive nodes are running at load 10 on 24-core, 48-hyperthreaded machines currently in the exclusive queue. This motivated the changes above.
